1 Claim. l

My invention relates to mechanics tools and has for an object to providea pair of tongs for handling electried or hot elements with safety.

Another object of this invention is to provide automatically actuatedtongs.

A further'object of the invention is to provide a pair of tongs havingan adjustable or removable jaw member.

A still further object of my invention is to provide a pair of tongs thehandle of which is of insulation material.

Another object of the invention is to provide a pair of tongs the jawsof which are provided with an insulation coat.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawing inwhich:

Figure 1 is a longitudinal sectional View of my tongs,

Figure 2 is a detail view of an insulator handle,

Figure 3 is an end View of Figure 2, and

Figure 4 is a section on line 4--4 of Figure 1.

v In the accompanying drawing as above enumerated and in the followingspecification, like characters of reference indicate like parts.throughout and in which Ill, indicates my invention, which comprises aninsulated handle I I, having bores I2 and I3, extending longitudinallythere-through with a terminal enlarged recess Ill, pivoted Within whichrecess is a trigger extension I5, of a jaw I6, pressing against the wallI'I, of the trigger is a cap I3, actuated by a spring I9, held in boreI3, by means of an insulator cap 29. The action of the spring upon thetrigger is to hold the jaw I6, into engagement with a jaw 2|, the shank2,2, of Which is held in the bore 62, by means of a set 4screw 23. Theshank 22, may be adjusted vto extend the jaw 2|, if necessary. The jawsI@ and 2l, as illustrated are provided with respective teeth 2li and2'5, which teeth may be of any desired formation. The jaws lli and 2 l,as well as the trigger IIS, may if so desired be provided with aninsulating coating on the surfaces 26 and 2l.

From the foregoing description it will be obvious that my safety tongsmay be used either for electrical or heated work from which elements theoperator or user of the tool will be protected from either shock or heatas the case may be.

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawing.Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size and rearrangement of details and parts such ascome within the purview of the invention claimed may be resorted to, inactual practice, if desired.

Having now described my invention that which I claim as new and desireto procure by Letters Patent is:

A pair of tongs comprising a slidable jaw, a pivoted jaw. an insulatorhandle for the jaws, said handle having a bore through which the rst jawoperates, said pivoted jaw being spring actuated andmanually controlled,said pivoted jaw having a trigger depending from the handle for saidmanual control, and a longitudinal here in the handle in which thespring is seated.
